Measurement of the inclusive jet cross section in pp collisions at √(s) = 2.76 TeV

The double-differential inclusive jet cross section is measured as a function of jet transverse momentum p_T and absolute rapidity vertical stroke y vertical stroke, using proton-proton collision data collected with the CMS experiment at the LHC, at a center-of-mass energy of √(s) = 2.76 TeV and corresponding to an integrated luminosity of 5.43 pb^-1. Jets are reconstructed within the p_T range of 74 to 592 GeV and the rapidity range vertical stroke y vertical stroke < 3.0. The reconstructed jet spectrum is corrected for detector resolution. The measurements are compared to the theoretical prediction at next-to-leading-order QCD using different sets of parton distribution functions. This inclusive cross section measurement explores a new kinematic region and is consistent with QCD predictions. (orig.)
